SAW-VISE SUPPORT.

SPECIFICATION forming part of Letters Patent No. 778,605, dated December27, 1904.

. Application filed May 5,1902. Serial No. 105,944.

To (all whom it may concern:

Be it known that I, TILLIAM M. POTTER, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Saw-Vise Supports,

of which the following, taken in connection with the accompanyingdrawings, is a full, clear, and exact description.

My invention relates particularly to a sawvise; and it consists in asimple means for adjustably securing the vise in position on anysuitable support, so that the saw may easily be adjusted in variousconvenient positions for filing.

The invention consists, essentially, of a clamping-piece to be securedon the bench, a semispherical boss on the clamping-piece, a cup-shapedpiece or vise-cup carrying the vise fitted to the boss,a second clamping-cup fitting over the first cup, and a thumb-screw to engage withthe clamping-cup and the boss, whereby the visecup and the vise carriedthereon are clamped securely in position.

My invention will be understood by reference to the drawings herewith,in which the same reference-numerals indicate the same parts in all thefigures.

Figures I and II are side elevations of my invention, showing thesaw-vise in two positions. Figs. III and IV are top plans illustratinglateral adjustment of the vise. Fig. V is a vertical section of theimportant parts of the clamping mechanism.

In the figures, 1 indicates the fixed jaw of the saw-vise, and 2 anintegral arm, to which the outer jaw 3 is pivoted at 4 and operated bylever 5.

7 is the clamp or clamping-piece, having upper and lower jaws 8 9, toone of which is fitted a suitable thumb-screw 10 for securing to thebench or other suitable support. This clamp is formed withreinforcing-ribs l1 and with a rounded boss 12, preferably substantiallysemispherical. To this boss is fitted the vise-cup 14, perforated at andprovided with the integral arm 16, arranged substantially at rightangles.

The saw-vise may be integral with the arm or connected thereto by anysuitable means, such as the bolt 17, engaging with a slot 18 in thevise.

To the vise-cup is fitted the clamping-cup 20, and the parts are allclamped firmly in position by means of the thumb-screw 21. By thissimple means the vise may be firmly clamped in any desired position andthe thumb screw easily loosened, so that the vise may be adjustedvertically or laterally or at any angle to bring the saw into positionmost convenient to be filed. By this construction the support for thevise is arranged near to its jaws instead of at its base, whereby thevibration is much reduced.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In the support for a saw-vise or similar device, the combination withthe clamp having a roundedboss on its upper end, and means to secure theclamp on a suitable support, of a concave clamping element formed to fiton top of the boss, and a thumb-screw to engage with the boss and theclamping element, whereby a part arranged between them and formedsubstantially to fit both may be secured firmly in position.

' 2. The combination in a saw-vise clamp, of a clamping-piece having arounded boss on its upper end, means to secure the clamping-piece on asuitable support, a vise-cup fitted to rest on top of the boss, aclamping-cup fitted to the vise-cup, and a thumb-screw engaging with theclamping-cup and the boss, to secure the saw-vise firmly and adjustablyin position.

3. The combination in a saw-vise clamp, of a clamping piece havingparallel jaws, a thumb-screw fitted to one of the jaws to secure theclamping-piece in suitable position,a solid, integral boss on theclamping-piece, a visecup fitted thereto, an integral arm on the visecuparranged at substantially right angles thereto, a bolt to connect thesaw-vise to the arm, a clamping-cup fitting over the vise-cup, said bossand the engaging faces of the two cups being spherically formed, and athumbscrew engaging with the boss and the clamping-cup and extendingthrough an opening in the vise-cup to clamp the parts securely inposition.

4. The combination in a saw-vise clamp, of a clamping-piece, means tosecure the clamping-piece on a suitable support, an integral boss on theclamping-piece, a vise-cup fitted to the boss, an arm on the vise-cup, avise, means to connect the vise adjustably to the arm, a clamping-cupadapted to fit over the vise-cup, said boss and engaging faces of thetWo cups being spherically formed, and a thumb-screw adapted to engageWith the boss and clamping-cup to secure the vise adjustably inposition.

5. The combination in a saw-vise clamp, of a clamping piece havingparallel jaws, a thumb-screw fitted to one of the jaws to secure theclamping-piece to the bench, a solid,

integral boss on the clamping-piece, a visecup fitted to the boss, anintegral arm on the vise-cup arranged at substantially right anglesthereto, a bolt to connect the saw-vise to the arm, the saw-vise havinga slot to fit the bolt, a clamping-cup fitting over the vise-cup, saidboss and the engaging faces of the two cups being spherically formed,and a thumbscrew engaging With the boss and the clamping-cup andextending through an enlarged opening in the vise-cup to clamp the partssecurely in position.

In testimony whereof I have hereunto signed my name.

WILLIAM M. POTTER.
